/B array
(Optional) An array of three numbers in the range 0.0 to 1.0 that shall specify the components in the DeviceRGB colour space of the background colour for the rectangle in which the media is being played. This colour shall be used if the media object does not entirely cover the rectangle or if it has transparent sections. It shall be ignored for hidden windows. Default value: implementation-defined. The conforming reader should choose a reasonable value based on the value of W. EXAMPLE 1 A system default background colour for floating windows or a user-preferred background colour for full-screen windows. If a media format has an intrinsic background colour, B shall not override it. However, the B colour shall be visible if the media has transparent areas or otherwise does not cover the entire window.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
